Genetic Improvement in Brazil: Breeding Efforts Improve SPF White Shrimp Performance

摘要

Aquatec, the leading shrimp-breeding company in Brazil with about 20% of the market for Pacific white shrimp postlarvae, has maintained a pedigreed genetic improvement program since 1996. Within a classical full-sib family structure relying on elastomer tagging of animals at sizes of 2-3 g for family identification, 60 full-sib families were initially produced every year.
